If you want to go down the AP path then get the best mount you can afford.
I had a similar choice and saved for the G11. that certainly doesn't mean you can't get good results with an eQ6, the longer focal length you go generally the better mount is required.
Although strangely enough This image has listed as it's mount listed as a 15 inch scope on an eq6
